Here's a curious situation hopefully someone can shed some light on.
I have a D750, an obsolete D100 (metaphorically) gathering dust, and the following lenses:
AF Micro Nikkor 60mm 1:2.8 D lens = works fine on D750 and my obsolete D100
AF-S Nikkor 17-35mm 1:2.8 D lens = works fine on D100, used to work fine on D750 but now gives fEE error
AF Nikkor 80-200mm ED 1:2.8 D lens = works fine on D100, used to work fine on D750 but now gives fEE error
Have cleaned contacts of each lens. Have of course locked the aperture ring of each lens while attempting to clear the fEE error on the D750. No luck. So I turned the sub-command dial off, and bingo (sort-of).
AF-S Nikkor 17-35mm 1:2.8 D lens + aperture ring option selected in f Controls submenu = no fEE error but aperture cannot be changed from f22 (that is, moving aperture ring does nothing)
AF Nikkor 80-200mm ED 1:2.8 D lens + aperture ring option selected in f Controls submenu = no fEE error but aperture cannot be changed from f22 (that is, moving aperture ring does nothing)
Seems to me it must be a camera body issue, as the lenses work on my old D100, but what have I done to the D750 for it to start returning a fEE error? Mechanical damage?
